Question

The velocity of light in vaccum is 3× 10 ^ 8 m/s . calculate the time taken by the travelled distance of 6× 10 ^14 m . ​

Answer 1

Answer:

2*10^8m/s

Explanation:

speed= distance/time

         =6*10^14/3*10^6

         =2*10^8 m/s

hope this helps you......

Answer 2

Answer:

This question can be solved using the classic equation of motion: distance = velocity * time.  We have two known parameters and one unknown parameter; however, in order to solve the problem we must first rearrange the equation to solve for time: time = distance / velocity.

distance = 1.5x10^11m

velocity = 3.0x10^8 m/s

Substituting into the equation:

time = (1.5x10^11m)/( 3.0x10^8 m/s) = 500 seconds

Therefore, light travelling at 3.0x10^8 meters per second takes 500 seconds (8 minutes, 20 seconds) to reach the Earth, which is 1.5x10^11 meters away from the sun.
